5. Notwithstanding section 4, in any building or separate part of a building including both category A and category B dwellings, a category B dwelling may be allocated only to a household whose applicant or head of the household within the meaning of section 1 of the By-law respecting the conditions for the leasing of dwellings in low-rental housing, (chapter S-8, r. 3), is not less than 50 years of age and in which the dependant children are not less than 16 years of age.
Notwithstanding the foregoing, the lessor may, by by-law, fix another age for the allocation of category B dwellings or allow them to be allocated to an applicant or head of the household who is a handicapped person without consideration of age.
